Beschreibung
Zusammenfassung:The element (10) has a sound waves absorption layer (12) attached on a surface (14) and including a pixel (20) and two coatings (16, 18), where the pixel is imprinted and attached on the surface by a peel-off film. Each coating has a pixel, where the pixel of the absorption layer is applied on the pixels of the coatings. The cross section of the pixel of one of the coatings (18) is larger than the pixel of the other coating (16). The pixel of the absorption layer is formed from an elastic material. An independent claim is also included for a method for manufacturing a sound waves absorption element. Die Erfindung betrifft ein Schallwellenabsorptionselement (10, 10', 10'', 10''', 10''') insbesondere für ein Kraftfahrzeug, bei welchem zumindest bereichsweise auf eine Oberfläche (14) wenigstens eine Schallwellenabsorptionsschicht (12) aufgebracht ist, wobei die Schallwellenabsorptionsschicht (12) wenigstens einen Pixel (20) aufweist.
